// Normally you would expect the contentInBuffer to contain the complete HTML code to return, but this is not always true because it is possible that
// the content that will be send back is larger than the buffer foreseen by ASP.NET (currently the buffer seems to be a little bit less than 16K)
// and in that case this method will be called multiple times, which might result in false positives being written to the logs for not finding a </body>
// in the current chunk.
// So we need to be able to deal with the following cases without writing those false positives
// 1 - the </body> tag is found
// 2 - the </body> tag was not found because
// 2.1 - the </body> tag will be available in one of the next calls because the total length of the output is larger than 16K
// 2.2 - the </body> tag is split up between this buffer and the next e.g.: "</bo" en "dy>"
// 2.3 - the </body> tag will never be available (is missing)
// 2.4 - Multiple </body> tags are available of which some might be part of a Javascript string or the markup is badly formatted
// The easiest way to deal with this is to look for the last match for the </body> tag and if it is found we write everything before it to the
// output stream and keep that </body> tag and everything that follows it (normally only a </html> tag but it can also be a 2.4 case) for the next call.
// In case there is no match for the </body> tag, then we write everything to the output stream except for the last 10 characters (normally the last 6 would suffice, but we take a little margin to reassure us somehow ;-)) which we keep until the next call.
// If there is a next call, then we first prepend the characters we kept from the previous call to the content inside the buffer (which might complete a chunked </body> tag for instance)
// and start our check all over again (which might result in finding a </body> tag or discarding a previously found </body> tag because that one was not the last one.
// Anyhow, as long as we are not a the end and a </body> tag has been found previously, the output will be buffered, just to make sure there is no other </body> tag further down the stream.
// If there is no next call, then the Flush method will be called and that one will deal with the current state, which means:
// - in case there was a </body> tag found, the replacement will be done
// - in case there was no </body> tag found, then the warning will be written to the log, indicating something went wrong
// either way, the remaining unwritten characters will be sent down the output stream.
